What is a super core assembly?

A super core assembly is the central part of a turbocharger, containing the compressor housing, compressor wheel, and the bearing system. It's the foundation upon which a complete turbocharger is built, typically requiring a separate turbine housing to function.

Why is 'reverse rotation' important for this turbo core?

Reverse rotation refers to the direction the compressor wheel spins. This configuration is necessary for specific engine builds, such as certain twin-turbo setups or custom manifold designs, where the airflow needs to be directed into the intake from a particular side.

What else is needed to make this a functional turbocharger?

To make this a complete, functional turbocharger, you will need to source and attach a compatible turbine housing. Additionally, supporting modifications for your engine, such as fuel system upgrades and custom tuning, are essential to utilize the performance potential of this core.

Product Details

The Garrett G30-660 Super Core features a forged-milled aluminum compressor wheel with a 66mm inducer. This specific unit is configured for reverse rotation, which is a key consideration for certain twin-turbo setups or unique manifold designs where the airflow path needs to be directed differently. It's built around Garrett's advanced G30 series technology, known for its robust construction and performance capabilities in demanding applications.

This super core assembly is designed for builders and tuners who need a high-performance, reliable foundation for a custom turbocharger. The G30-660 is a popular choice for its ability to support significant horsepower while maintaining good response, making it suitable for a wide range of performance builds. The forged-milled compressor wheel offers improved durability and lighter weight compared to cast wheels, contributing to quicker spool times. Its robust bearing system is built to handle the high speeds and temperatures associated with forced induction.

When building a custom turbocharger, starting with a quality core assembly like this Garrett unit is crucial. It provides the essential components – the compressor housing, wheel, and bearing system – that form the heart of the turbo. You'll need to source or fabricate the turbine housing and connect it to your exhaust manifold and downpipe. Ensure you have the necessary supporting modifications, such as fuel system upgrades and engine tuning, to take full advantage of this core's potential. This part is not CARB approved and cannot be shipped to California.
